Cost-to-cost revenue accrual method - Automatically reverse the revenue event

We have a requirement to use the cost-to-cost revenue accrual method and I have done basic testing and it works according to our requirement but the only problem is that we want to automatically reverse the revenue event so that every month, the entry is ITD.

Can someone point me in the right direction regarding how to do this via standard functionality or other ways of going about this if you have had same requirement?

Thank you in advance!
